Hello,

 

The correct join operation in tMap is MAIN_FLOW to LOOKUP_FLOW

The join you are trying to establish (LOOKUP_FLOW to LOOKUP_FLOW) is wrong.

 

Work-Around: Use separate tMap where you have to join outcome of first tMap as main and other join as lookup.

Something like this: 

MAIN=>tMap1(join LOOKUP1)=get lookup-value>tMap2(join LOOKUP2)=get lookup-value=>tMap3(join LOOKUP3)=get lookup-value=>TARGET.

 

Thanks,

Jagadish.
